Please refer to fig. 1, 2 and 3, which are only illustrative and not intended to limit the scope of the present utility model. As shown in the drawings, the wind collecting fan 1 of the present utility model comprises a hub 10, a fan blade device 20 and a plurality of wind collecting plates 30; the hub 10 may be formed by plastic injection molding and is located at the center of the wind collecting fan 1.
The fan blade device 20 may be formed by integrally injection molding plastic to form a plurality of fan blades 21, where the plurality of fan blades 21 extend from the outer periphery of the hub 10 and are radial arc plates, each fan blade 21 includes a wind-driving surface 21A, a leeward surface 21B formed on the back side of the wind-driving surface 21A, the fan blade 21 has a connecting end edge 211 adjacent to the hub 10 and a separating end edge 212 far from the hub 10, and an air-in edge 213 and an air-out edge 214 are formed at the connection between the wind-driving surface 21A and the leeward surface 21B.
The air collecting plates 30 are respectively arranged on the fan blades 21, the air collecting plates 30 can be formed by plastic injection and are integrally formed with the fan blades 21 in a strip shape, and the air collecting plates 30 are arranged on the air driving surfaces 21A of the fan blades 21 and are adjacent to the separation end edges 212; the wind collecting plate 30 has a leading edge 31 and a trailing edge 32 opposite to the wind-driving surface 21A of the fan blade 21, and gradually extends from the leading edge 31 toward the trailing edge 32 to increase in height, the wind collecting plate 30 extends above the trailing edge 32 to form a wind collecting extension 33, the wind collecting extension 33 is formed as a thin strip, the wind collecting extension 33 is connected to the leeward surface 21B of the other fan blade 21 adjacent thereto, and a wind collecting opening 34 is formed below the wind collecting extension 33 and at the trailing edge 32, the wind collecting opening 34 is located at the outer edge of the wind outlet 214 of the fan blade 21 and also at the trailing edge of the wind outlet 212 and the trailing edge 32 in the fan rotation direction.
Furthermore, the wind inlet side 213 of the fan 21 is formed with a wind inlet 35 along the wind-driving surface 21A, in other words, the wind inlet 35 is formed between the wind inlet side 213 of one fan 21 and the leeward surface 21B of the other fan 21 above, so that the air flow can enter. An air outlet 36 is formed at the air outlet edge 214 of the fan blade 21, that is, the air outlet 36 is formed between the air outlet edge 214 of one fan blade 21 and the leeward surface 21B of the other fan blade 21 above, and the air outlet 34 formed by the air collecting extension portion 33 and the tail end 32 is arranged outside the air outlet 36, so that the air outlet 34 is also laterally corresponding to and communicated with the air outlet 36, and thus, the air flow formed by the operation of the fan can be discharged downwards through the air outlet 36, and the air flow is accelerated to flow in and out through the air collecting operation of the air collecting fan 1.
In the above-mentioned structure, each wind collecting plate 30 is disposed at the position of the wind-driving surface 21A adjacent to the off-end edge 212, and is connected to the leeward surface 21B adjacent to the other fan blade 21 by the wind collecting extension portion 33, so that the plurality of fan blades 21 are connected through two phases of the wind collecting plate 30 to form an integral annular connection.
In the preferred embodiment, the leading edge 31 of the air collecting plate 30 is adjacent to the separating edge 212 and the air inlet edge 213, i.e. is kept at a proper distance from each other, and the trailing edge 32 is aligned with the separating edge 212 and the air outlet edge 214, i.e. the air collecting plate 30 is not aligned with or parallel to the separating edge 212, so that the air quantity adjusting and controlling effects can be generated, and the noise can be greatly reduced during the operation of the air collecting fan 1 by the arrangement of the air collecting plate 30.
Referring to fig. 4 and 5 together, to illustrate the application state of the improved structure of the wind-collecting fan of the present utility model, the wind-collecting fan 1 is rotatably disposed on a base 40 (in this embodiment, the base is a heat sink module), the base 40 is disposed on a heat generating module/heat generating component 50 in contact with the heat generating module/heat generating component 50, such as a CPU, a chip or other electronic components/modules, etc., when the wind-collecting fan 1 is started to rotate the hub 10, the plurality of blades 21 also rotate along with it, and the air flow generated when the wind-collecting fan 1 rotates can enter between two adjacent blades 21 through the air inlet 35, and is discharged from the air outlet 36 at the air outlet edge 214 to act on the heat generating module/heat generating component 50 for heat dissipation. And, at the same time, due to the arrangement of the wind collecting plate 30, the wind collecting and accelerating effects are provided at the air outlet 36, so that the air pressure at the end edge 212 of the fan blade 21 and the air pressure at the outer side of the wind collecting plate 30 are relatively increased, and based on the cypress's effort principle, the air at the end edge 212 and the air at the outer side of the wind collecting plate 30 enters the fan blade device 20 through the wind collecting opening 34, and the air displacement of the air outlet 36 is increased.
The improved structure of the wind collecting fan of the utility model is formed by the wind collecting plates 30, and each wind collecting plate 30 is formed by plastic injection and is integrally formed with each fan blade 21, so that when the hub 10 drives each fan blade 21 to rotate, air flow caused by rotation is shielded by each wind collecting plate 30 to generate wind collecting effect, namely, the wind inlet and the wind outlet of the wind collecting fan can be greatly improved, and noise generated at the wind inlet 35 and the wind outlet 36 of the wind collecting fan 1 is reduced.
The improved structure of the wind collecting fan can greatly improve the wind inlet and outlet of the fan by the structure, so that the wind collecting fan has excellent wind collecting effect, and further, the economic benefit and practicability of the use of the fan are positively achieved.
Thus, the above description has been made in detail with reference to the accompanying drawings to illustrate the embodiments of the improved structure of the wind-collecting fan of the present utility model and its technical features and functions. It should be emphasized, however, that the foregoing detailed description is directed to specific embodiments of the present utility model, which should not be construed as limiting the scope of the utility model, but rather as limiting the scope of the utility model as defined by the appended claims.
